TELEPHONE ATTACHMENT. '4

Application filed November 9,1909 Serial No. 627,080

,To all whom {it may cance -m;

- Be it known that. I, JAMES A. Penny, cit-izenofthe United States, residing at Bidwell, inthe eountyjof \Vapello and State of Iowa, have invented certain new and useful Im rovements in Telephone Attachments, of

which the following is a specification.

My invention relates to an attachment adapted to be applied to telephoneswhereby of a telephone at one .time.

The invention consists of a su port for a a number of .users may listen at the receiver tele hone receiver upon which t ereceiver v is a apted to be placed and used with the attachment, a sound' chamber and a plurality of tubes extending from the sound chamber and preferably provided at their extremities with means whereb the ends of the-tubes maybe applied to t e ears of the users.

My invention is shown in theaceompany in" drawings, wherein r I igure 1 IS a perspective v ewer; my invention; Fig. 2 1s a fragmentary section thereof; and Fig. 3 is a perspective view of a modification.

- Corresponding and like parts are referred to in the followin description and indicated in all the viewso the drawings by the same reference characters.

Referring to the figures,2 designates a base plate aving thereon a casing .3, said casin .formed in its'interior with "a sound --cham er 4 of any desired character, which is closed at its lower end, preferably by a plate v w iich are inserted t 1e inner extremities of a i tubes 5 rovided with alurality 'of openings .in

plurality of sound conductin tubes-6, these referably being of ru ber. The end of eaci tube 6 is provided with a cup 7 ported upon the casing 3 so that the, vibrathrough which the tube projects, the cu being designed to be applied to theear o the user and the projectingtube entering the opening of the ear so that the sound is car: ried more directly to theauditory nerve. Preferably, the casing 3 is supported upon 'the legs 8, though this is not necessary, as

the attachment'might be applied to a wall or other convenient support by means ofthe base plate 2.- I have shown the casing 3 as formed of a block of any suitable material,

having thechamber 4 formed therein, this chamber being preferably tapered toward its outlet, end. The upper face of the casing 3 is formed so as to contact with the rim of a telephorie receiver when the receiver is sup- -close the barrel of the telep outer ends of the wire being outwardly bent so as to permit the easy insertion of the receiver. .he upper face of the casin r 3 is er, felt or other suitable-material which fits the rim of the receiver so that the receiver w ll have a good air tight connection with the upper face of the box 3 so that no sound may 6 lost. The operation of my invention will be obvious. \Vhen it is desired that a number of people shall bear the message which is coming over the telephone wire, it is only necessary to remove the receiver from its hook and place it within the holder with the rim of the receiver resting upon the felt ring 11. Those who are desirous of listening to the message can each take one of the rubber tubes 6 and placing the ear piece thereon to the ear listen to the conversation.

Mv invention is simple, can be easily applied. does not require any change in the telephone now in use, permits the telephone ,to be used as ordinarily and yet'permits on an occasion a number of listeners to hear ,what 1s said on the phone.

/= It will be obvious tha the tubes or pipes 6 may be of any desire length and might extend to a: number of dul er-cut places in a building so that ersons in dili'erent parts of the samebui] ing could hear whatever was being telephoned to thercentral 'oflice. andthis witlioutany change in the usual telephone connections.

Vt-hileI have shown what I believe to be the preferable'formof my invention. I do not wish to be limited thereto as it is obvious that man changes might be made therein withoutdeparting from the spirit of the-invention.

Having ,thus described the.invention,"what is claimed as ncwis:

'1. An attachment fortelephones, contione receiver, the.

referably provided with a ring 11 o rubreceiver holder" mounted adjacent to. the

* prising a base plate, the ease plate and open end of the chamber and adapted to hold a telephone receiver with its rim in en gagement therewith.

2. An attachment for telephones, comsaid casing having therein a chamber, one end of the chamber being open, a plurality of conducting tubes extending from the other end of the chamhery-a ring of yielding materialmounted on the open end of the chamber and adapted to engage with the rim' of a telephone receiver, and a clamp a casing mounted on pro ectlng therefrom,

mounted on the base late ancl'adapted to en age the barrel of the telephone receiver and hold the receiver 'with'lts riinin engagement with said ring. I

3. An attachment for telephones, comprising a base plate, a'casing mounted on' the base plate, said casing being hollow to open at one end, a

form a sound chamber plurality of tubesextending from the other end of the sound chamber adjacent to the open end and adapted to support a telephone receiver with its rim in contact with the open end of said casin and legs for supporting said casing and base. i i

In testimony whereof I aflix my signature in presence of two. witnesses.
